A full sized mattress is 54x75"
A Queen sized mattress is 60x80"
With a 6' wide (72") trailer, neither of the above store-bought mattresses would fit cross-ways in your new trailer; and, regardless, 72" is problematic for many people because it isn't long enough to allow the feet to stretch out well, unless you're not very tall.
Also, don't short yourself on the doors or windows. Make certain that you have two exits; one, for standard use and one, for emergencies.
Further, you never know what type of person your future wife will be. She may be the type that wants an indoor porta-potty.
Remember, there's a good chance that this will be the last trailer you will make; so, don't skimp on something that you'll be sorry about later.
There's no reason to rush building this trailer. Take your time and do it right.
